Title: Improvements in and relating to the decomposition of ammonia
Inventor: BREITBACH FRITZ
IPC: F23G7/06
Filed: 1964-05-25
Abstract: Ammonia contained in the gases obtained from the scrubbing water and/or condensates produced in the manufacture of coke oven gas is decomposed to N2 and H2 without formation of NO by directly or indirectly heating the gas mixture to the decomposition temperature, conducting the gas mixture at that temperature through a decomposition zone packed with heat-resistant packing material or a catalyst and cooling the mixture to 150-200 DEG  C.  The hydrogen is oxidized to water by introducing air and the heat of combustion may be utilized. In the case of direct heating a gaseous or liquid fuel is mixed with the ammonia-containing gas and air not exceeding that required for the combustion of the fuel is added.  The ammonia content of the gas may have been increased by multi-step distillation.  The cooled gases may be united with the crude gas of the generating plant prior to or after scrubbing to remove H2S, or they may be mixed with H2S-containing fumes from a gas scrubber and the mixture burned in the furnace of a sulphuric acid plant.
